Beschreibung
Zusammenfassung:	The invention discloses an asymmetric donor-receptor-donor type conjugated polymer based on 5-fluoro-2,1,3-benzothiadiazole and application thereof in the field of electrochromism. The structural formula of the asymmetric donor-receptor-donor type conjugated polymer based on 5-fluoro-2,1,3-benzothiadiazole is shown in the specification. According to the invention, a dibromo-5-fluoro-2,1,3-benzothiadiazole monomer and a stannide of Ar are mixed and subjected to a Stille reaction so as to obtain a polymerization precursor, and the polymerization precursor is subjected to electrochemical polymerization to obtain the conjugated polymer. The conjugated polymer has high intermolecular binding energy and large dipole moment due to introduction of the asymmetric structure 5-fluoro-2,1,3-benzothiadiazole, so donor/acceptor interaction is enhanced, and electrochromic optical contrast and electrochromic developing efficiency are improved; and the conjugated polymer is an excellent electrochromicfunctional layer, and a c
